BIS-[2-(2-METHYL-3-BUTANONE OXIME)] HYDRAZINE

C10H22N4O2, Mr = 230.31, triclinic, P1BAR, a = 12.010(5), b = 13.188(9 ), c = 9.163(2)angstrom, alpha = 107.30(4), beta = 108.35(3), gamma = 77.42(2)-degrees, V = 1303.(1) angstrom3, Z = 4, D(x) = 1. 174(2) g cm -3, (MoKalpha) = 0.71073 angstrom, mu = 0.78 cm-1, F(000) = 504, T = 2 97 K, R = 0.039, R(w) = 0.054 for 3023 observed reflections (of 4521 u nique data). The hard, transparent, colorless crystals give sharp, int ense diffraction peaks; this may be related to the strong three dimens ional hydrogen bonding involving the oxime groups as well as the hydra zine hydrogens. Bond distances and angles as well as torsion angles ar e in good agreement for the two independent molecules and are normal. Although there is near two-fold symmetry relating the two molecules, p ositions of neighboring groups removes a twofold crystallographic axis .
